in this study, we examined the antioxidant activities of methanolic extract of three endemic species of salvia from iran (s. lachnocalyx, s. reuterana and s. sahendica) employing various established in vitro systems including ferric reducing antioxidant power, trolox equivalent antioxidant capacity assay and scavenging of 1,1-diphenyl-2-picrylhydrazyl radical. the results revealed that s. reute...

The antiarthritic drug, aumnofin ("Ridaura’) is an orally-active antiarthdtic drug containing linear Au(I). The gold is co-ordinated by triethylphosphine and the sulfur of tetraacetyl-I-D-1thioglucose (HSATg). Deacetylation occurs during absorption and then the thioglucose is displaced via ligand displacement reactions. Over 80% of the gold in the blood is carded by serum albumin, a 66 kDa sing...

Semiconductor nanoparticles (quantum dots) are promising fluorescent markers, but it is very little known about interaction of quantum dots with biological molecules. In this study, interaction of CdTe quantum dots coated with thioglycolic acid (TGA) with bovine serum albumin was investigated. Steady state spectroscopy, atomic force microscopy, electron microscopy and dynamic light scattering m...

The response of strain 2 guinea pigs to limiting doses of bovine serum albumin is under dominant genetic control linked with the poly-L-lysine gene. Inbred strains 2 and 13 guinea pigs make similar antibody responses to 10 mug bovine serum albumin, whereas strain 2 but not strain 13 animals produce significant amounts of antibodies in response to 0.1 mug. The relationship between the presence o...

Spinach chloroplasts were immobilized with vinyl monomers by radiation-induced polymerization at low temperature and stored in buffer containing bovine serum albumin. The lifetime of O(2) evolution activity in photosystem II was prolonged remarkably in immobilized chloroplasts. Thermostability of immobilized chloroplasts stored in buffer containing bovine serum albumin was far better than that ...

Glycophorin both in solution and inserted into liposomes blocks invasion of erythrocytes by the malaria parasite Plasmodium falciparum. Furthermore, one sugar, N-acetyl-D-glucosamine (GlcNAc), completely blocks invasion of the erythrocyte by this parasite. GlcNAc coupled to bovine serum albumin to prevent the sugar entering infected erythrocytes was at least 100,000 times more effective than Gl...

As an initial step towards creating genetically modified cattle as a biopharming source of recombinant human serum albumin (rHSA), we report modification of the bovine albumin (bA) locus by transcription activator-like effector nuclease (TALEN)-stimulated homology-directed repair (HDR). Pedigreed bovine fibroblasts were co-transfected with TALENs and an 11.5-kb human serum albumin (HSA) minigen...
